Sometimes people use iptables -j TCPMSS --set-mss on routers in order to

It is only a dodgy patch, not a real workaround.
Is it useful to have this rule on server? For example, if someone

IMHO not really.
While it does help somewhat for TCP traffic when there is PMTU blackholes,
it does reduce the efficiency somewhat for everyone else.
